This clip is a version of this one
but remastered to make it watchable. The video seemed originally captured on a mobile phone camera (hinted from the use of the h263 codec, the low resolution, poor audio and shaky image), thus the need for a clean up.
The following adjustments were made:
- Image stabilized. The original was very shaky, which might be understandable when holding a 100 grams gadget pointed in a direction for 2 hours without stationary support.
- Image deblocked. The original had large amounts of blocking which had to be removed since this is a lossy transcode (a lossy transfer from one format to another)
- Audio levels adjusted. The audio was barely audible to begin with.
- Audio noise reduced. The noise floor was rather high compared to the average volume making it very difficult to discern the speech.
- Audio low pass filtering applied. The sound appeared rather aliased.
Further enhancements possible but not tried (for those with CPU cycles to burn):
- Increase video resolution (information in the frames) using super resolution techniques. Likely very difficult due to the low frame rate coupled with large changes plus absence of image aliasing.
- Increase video frame rate using motion vector estimation and interpolate/construct delta frames using those vector values. This might raise the frame rate to at least 23,976 fps (same as feature film).
